We often get the question, "Do you Cine-Mod Canon lenses?" The answer is, yes. ...and no.
It's always best to see the lens(es) in person to know 100% what mods we're able to perform and whether or not the mod will enhance or hinder the lens performance. Typically we can add a focus gear, zoom gear, and front ring with a cap, as we did to the lenses featured in this entry. De-clicking is not an option for Canon L series lenses because, well... There isn't an iris mechanism to be de-clicked. You can't remove what isn't there! Modern Canon lenses use tiny motors to control the iris setting which don't utilize any sort of "click" mechanism.
Adding our standardized focus and zoom gears allow the operator to pair the lens with a manual or wireless follow-focus or zoom motor to control the movement more precisely. Adding the focus gear alone doesn't increase the focus rotation, but using the correct control device in conjunction with the Cine-Mod® gear will certainly provide a much longer, more accurate focus pull.
